Hi all,
this is just a heads-up for people that might encounter a similar problem.
I'm using boost::thread for creating CPU processing threads after I've
started an osg::Viewer. I've been pulling my hair out over the fact that
all my threads end up on the same processor.
It turns out that the default single threaded viewer sets the affinity
of its thread (the main process iow) to CPU0. All my user threads
created after this end up on CPU0 too, because they inherit the affinity
of the main process.
I've had to manually set the affinity of the main process after creating
the viewer (I couldn't find an OSG call though, had to use a pthreads
call on Linux) or set the affinity of the user threads once created.
regards
jp
